Services - Storage Flashcards
1
Q
FSx - Characteristics
A
- Provides a managed third-party FS with the native compatibility and feature sets for workloads such as Microsoft Windows–based storage, high-performance computing, ML, and electronic design automation
- Supports three file system types: Lustre, NetApp ONTAP, and Windows File Server
- Provides incremental backups
- Automatically encrypts data at rest using KMS keys, and data in transit using SMB Kerberos session keys
2
Q
FSx - FSx for NetApp ONTAP
A
- Provides fast and flexible shared file storage (SSD) accessible from Linux, Windows, and macOS compute instances running in AWS or on-premises
- Supports NFS, SMB, and iSCSI protocols. Provides Multi-AZ deployments
- Provides automatic data tiering, based on access frequency, to reduce costs
- Offers data compression, deduplication, and compaction to reduce storage consumption
3
Q
FSx - FSx for Windows File Server
A
- Provides managed Microsoft Windows file servers, backed by a native Windows FS
- The primary resources are FS and backups. A FS is made up of one or more Windows file servers and storage volumes
- Components:
- Windows file servers: A FS can have one or more Windows File Servers
- Storage volumes
4
Q
FSx - FSx for Lustre
A
- Open source Lustre FS is used for workloads where speed matters, such as ML, high performance computing (HPC), video processing, and financial modeling
- Data compression feature automatically compresses new files before they are written, and automatically uncompresses them when they are read
- Can be linked to S3 buckets, and on-premises data stores
- EC2 instances, and containers running ECS / EKS can access to FSx for Lustre FS
5
Q
Storage Gateway - Characteristics 1
A
- It enables hybrid cloud storage use cases
- On-premise services permitted:
- File storage, Volume storage, and Tape storage
- AWS services permitted:
- S3, S3 Glacier, S3 Glacier Deep Archive
- EBS snapshots
- All the gateway types support a virtual machine, an EC2 instance or a hardware appliance
6
Q
Storage Gateway - Characteristics 2
A
- Supports multiple protocols: NFS, SMB, and iSCSI
- Allows Local caching for on-premises applications
- Provides optimized data transfers
- Offers encryption in transit
- Can connect on-premise with AWS using HTTPS, AWS Direct Connect, or AWS VPN
7
Q
Storage Gateway - Types
A
- File gateway: by using NFS or SMB protocol it first looks into Local cache, otherwise goes to S3
- Volume gateway
- Tape gateway
8
Q
Storage Gateway - Volume gateway
A
- The application use iSCSI to request for a target where a stored or cached volume exist in the on-premise. Then goes into the respective AWS service
- EBS snapshots can be generated once the request is done or according to schedules (incremental backups that capture only the changes)
- The upload buffer is a staging area where modified data is stored previous to transfer it to AWS Storage Gateway, and then to S3
9
Q
Storage Gateway - Volume gateway modes
A
- Cached mode: a cached volume that stores frequently accessed data. In AWS volume stores can be created up to 32 GB size
- Stored mode: all the data is stored in on-premise. Asynchronous backups are performed in S3, as EBS snapshots
10
Q
Storage Gateway - Tape gateway
A
- Works with an existing backup application known as Virtual Tape Library (virtual media changer or virtual tape drives)
- Can work with an existing virtual tape application
- Each virtual tape is stored in S3. If no longer needed can be moved to S3 Glacier / S3 Glacier Deep Archive
- Not accessible to users outside of Storage Gateway
11
Q
Storage Gateway - Pricing
A
- File gateway (S3): charged by storage, request and data transfer pricing
- Volume gateway: charged by storage (S3 and EBS snapshots) and request and data transfer pricing
- Tape gateway (S3 Glacier / S3 Glacier Deep Archive): charged by storage (S3 and EBS snapshots) and request and data transfer pricing
